Concept:The /z/ sound is a voiced hissing consonant, which can be formed by letters such as “s” or “x”.
Explanation:The word “exist” is pronounced as /ɪɡˈzɪst/.
Here, the letter “x” is pronounced as /ɡz/, and this combination contains the /z/ sound.
So the required /z/ sound is present in “exist”.
Check the other options: “lice” ends with /s/, “leave” has /v/, and “measure” has /ʒ/.
Therefore, only option B correctly contains the /z/ sound.
Answer:B. exist
